Great sex positions: The Earthquake

Forget your average lip or knee trembler, this raunchy position will invoke a full-on body tremor

The Earthquake is not for the faint-hearted; a strenuous position that requires some strong upper thigh and leg muscles from you and your bloke, plus a good sense of balance and rhythm from you. Still, don't let that put you off, as The Earthquake will rock your world if you get it right.

For this position, stand with your lover in your bedroom doorway (that's why this position is called The Earthquake!) and make sure there's no chance of being disturbed by anyone else if you happen to live in a house or flat share.

Ask your lover to lean back against the door frame so that he's facing you with his back against the frame and his legs outstretched in an almost diagonal direction along the floor towards the opposite side of the door frame, with his feet planted firmly on the floor.

Once your lover is in position, straddle him in an almost upright position using your upper thigh and leg muscles to support you (almost as though your squatting in mid air) and your arms outstretched and resting on the door frame that your lover is leaning against. Once that's done, sit on your lover's cock and enjoy as deep or as shallow penetration as you like.
